Description

L'invention concerne un système pour collecter à distance des données, en particulier des données issues d'une pluralité d'installa­tions d'élevage de bétail.The invention relates to a system for remote collection of data, in particular data from a plurality of livestock facilities.

Une installation d'élevage de bétail est approvisionnée en aliments, tels que des farines ou des grains. L'éleveur y surveille la consommation desdits aliments par les animaux pour pouvoir la comparer aux recommandations du fabricant et leurs stocks pour pouvoir passer des commandes au moment voulu. Afin de gérer efficacement une telle installation, il doit posséder une connaissance exacte de ces différents paramètres.A livestock facility is supplied with food, such as flour or grain. The breeder monitors the consumption of said feed by the animals in order to compare it with the manufacturer's recommendations and their stocks so that they can place orders at the right time. In order to effectively manage such an installation, he must have an exact knowledge of these various parameters.

Au niveau du fabricant d'aliments, on gère les commandes d'aliments issues des différentes installations d'élevage. On rend visite aux éleveurs afin de leur présenter de nouveaux aliments. On répond rapidement à leurs questions, on analyse et résoud leurs problèmes, par exemple, d'ordre technique, sanitaire ou économique. Afin d'intervenir efficacement, on doit posséder une connaissance exacte et précise de tous les paramètres et caractéristiques des installations d'élevage des clients.At the level of the food manufacturer, we manage the orders of food from the different breeding facilities. We visit farmers to introduce them to new feeds. We quickly answer their questions, analyze and solve their problems, for example, technical, health or economic. In order to intervene effectively, one must have an exact and precise knowledge of all the parameters and characteristics of the clients' breeding facilities.

Le but de l'invention est de donner aux éleveurs et au fabricant la possibilité d'utiliser des outils informatiques pour leur permettre d'effectuer une gestion et un suivi technique, sanitaire et économi­ que, les uns, de leur installation, l'autre, de l'ensemble des installations d'élevage qui s'approvisionnent chez lui. Pour que cette utilisation soit réellement efficace, il est nécessaire que les données concernant tous les paramètres, les caractéristiques et les éléments variables de chacune des installations d'élevage soient mesurées et stockées in situ. Elles sont ensuite lues et transmises pour être traitées et analysées, soit par des programmes informatiques de gestion d'une installation d'élevage, soit par des programmes pour une gestion globale ou particulière de toutes les installations clientes du fabricant.The object of the invention is to give breeders and the manufacturer the possibility of using computer tools to enable them to carry out management and technical, health and economic monitoring. that, some, of their installation, the other, of all the breeding facilities that are supplied from him. In order for this use to be truly effective, it is necessary that the data concerning all the parameters, characteristics and variable elements of each of the breeding facilities be measured and stored in situ. They are then read and transmitted to be processed and analyzed, either by computer programs for managing a breeding facility, or by programs for global or specific management of all of the manufacturer's client facilities.

Ainsi, le fabricant peut, par exemple, suivre l'évolution de la consommation d'aliments par les animaux de ses clients et déterminer si cette évolution est normale au regard, d'une part, de ses propres recommandations et, d'autre part, de l'évolution du poids que prennent ces animaux. En fonction des paramètres et résultats de mesure obtenus sur une installation, il peut mettre en oeuvre les moyens nécessaires pour répondre à une question donnée de l'éleveur ou effectuer une livraison ou prodiguer les conseils appropriés. L'éleveur, quant à lui, peut suivre localement l'évolution de ses stocks et de la consommation d'aliments par ses animaux.Thus, the manufacturer can, for example, follow the evolution of the consumption of food by the animals of his customers and determine if this evolution is normal with regard, on the one hand, to his own recommendations and, on the other hand , of the evolution of the weight which these animals take. Depending on the parameters and measurement results obtained on an installation, he can implement the means necessary to answer a given question from the breeder or make a delivery or provide appropriate advice. The farmer, for his part, can follow locally the evolution of his stocks and the consumption of food by his animals.

Sur le site local 2, sont installés un micro-ordinateur 9 où peuvent être traitées toutes les données concernant l'installation d'élevage, telles que le nombre d'animaux, leur consommation en aliments solide et liquide, leur poids au jour le jour, etc., et un terminal de télécommunications 10 permettant de transmettre des données au fabricant et d'en recevoir par une ligne téléphonique L.On the remote site, at least one solid food storage silo 6 is installed, at least one liquid food distributor 7 and at least one weighing scale 8. On the local site 2, a microcomputer 9 is installed where all data concerning the breeding facility can be processed, such as the number of animals, their consumption of solid and liquid food, their day-to-day weight, etc., and a telecommunications terminal 10 making it possible to transmit data to the manufacturer and to receive it by a telephone line L.

Des dispositifs d'émission sur le site distant 1 transmettent des données, via le réseau de distribution 3, à un dispositif de réception 11, sur le site local 2, dont les sorties 12, 13 sont respectivement reliées au micro-ordinateur 9 et au terminal 10.Transmitting devices on the remote site 1 transmit data, via the distribution network 3, to a reception device 11, on the local site 2, the outputs 12, 13 of which are respectively connected to the microcomputer 9 and terminal 10.

Chaque dispositif d'émission est prévu pour recevoir les signaux d'un capteur soit de température, soit de poids, soit d'hygométrie, etc. Ainsi, dans le système représenté à la Fig. 1, un capteur de pression 14 monté sur le silo de stockage 6 délivre, à un premier dispositif d'émission 15, un signal analogique représentatif du poids d'aliment solide présent dans le silo 6. Un capteur de débit 16 monté sur le distributeur d'aliment liquide 7 délivre, à un second dispositif d'émission 17, un signal analogique représentatif de la quantité de liquide fournie, pendant un certain temps, par le distributeur 7. Un capteur de pression 18 monté sur la bascule 8 délivre à un troisième dispositif d'émission 19, un signal analogique représentatif du poids mesuré. Un capteur 20, qui peut, par exemple mesurer la température ambiante ou l'hygrométrie, délivre un signal analogique à un quatrième dispositif d'émission 21. Le nombre de capteurs et de dispositifs d'émission associés, tels que représentés ici, n'est pas limitatif.Each transmitting device is designed to receive signals from a sensor, either of temperature, of weight, of hygiene, etc. Thus, in the system shown in FIG. 1, a pressure sensor 14 mounted on the storage silo 6 delivers, to a first emission device 15, an analog signal representative of the weight of solid food present in the silo 6. A flow sensor 16 mounted on the distributor of liquid food 7 delivers, to a second emission device 17, an analog signal representative of the quantity of liquid supplied, for a certain time, by the distributor 7. A pressure sensor 18 mounted on the rocker 8 delivers to a third transmission device 19, an analog signal representative of the measured weight. A sensor 20, which can, for example measure the ambient temperature or the humidity, delivers an analog signal to a fourth transmitting device 21. The number of sensors and associated transmitting devices, as shown here, does not is not limiting.

On remarque, entre le compteur d'énergie électrique 4 et le réseau de lignes 3, la présence d'un filtre coupe-bande 22 qui évite que les signaux transmis entre les dispositifs d'émission 15, 17, 19, 21, d'une part, et le dispositif de réception 11, d'autre part, soient présents au-delà du compteur 4, côté réseau public de distribution. De plus, dans le cas d'un réseau de lignes triphasé, ce filtre établit un pont électrique pour les signaux transmis entre les trois phases.Note, between the electric energy meter 4 and the network of lines 3, the presence of a notch filter 22 which prevents the signals transmitted between the transmitting devices 15, 17, 19, 21, from on the one hand, and the reception device 11, on the other hand, are present beyond the counter 4, on the public distribution network side. In addition, in the case of a three-phase line network, this filter establishes an electrical bridge for the signals transmitted between the three phases.

La Fig. 2 représente un schéma synoptique de l'un des dispositifs d'émission, par exemple le dispositif 15 de la Fig. 1. Il comprend essentiellement une unité de traitement de données 30 reliée par un bus de données 31 à une mémoire 32, un convertisseur analogique/numé­rique 33 et une interface 34, reliée elle-même, par trois fils 35, 36, 37, à une entrée de signal E, une sortie de signal 5 et une entrée de sélection de mode ESM d'un émetteur/récepteur 38. Des entrées/sorties E/S1, E/S2 de celui-ci sont reliées à un enroulement 39 d'un transformateur d'isolation 40 dont l'autre enroulement 41 est relié au réseau de distribution 3.Fig. 2 represents a block diagram of one of the transmission devices, for example the device 15 of FIG. 1. It essentially comprises a data processing unit 30 connected by a data bus 31 to a memory 32, an analog / digital converter 33 and an interface 34, itself connected, by three wires 35, 36, 37, to signal input E, signal output 5 and signal input ESM mode selection of a transmitter / receiver 38. Inputs / outputs E / S1, E / S2 thereof are connected to a winding 39 of an isolation transformer 40 whose other winding 41 is connected to the distribution network 3.

La mémoire 32 est en fait constituée d'une mémoire de programme et d'une mémoire vive où peuvent être stockées des données. Le convertisseur 33 reçoit sur son entrée 42 les signaux analogiques délivrés par le capteur 14 associé au dispositif d'émission 15 et les convertit en signaux numériques directement exploitables par l'unité 30. L'interface 34 permet à l'unité 30 d'envoyer ou de recevoir des signaux à l'émetteur/récepteur 38, en particulier, avec son entrée E et sa sortie S, et de commander son mode de fonctionnement, émission ou réception, par son entrée ESM.The memory 32 is in fact made up of a program memory and a random access memory where data can be stored. The converter 33 receives on its input 42 the analog signals delivered by the sensor 14 associated with the transmission device 15 and converts them into digital signals directly exploitable by the unit 30. The interface 34 allows the unit 30 to send or to receive signals at the transmitter / receiver 38, in particular, with its input E and its output S, and to control its operating mode, transmission or reception, by its input ESM.

La Fig. 3 représente un schéma synoptique du dispositif de réception 11 du système de collecte de données de l'invention. Il comprend essentiellement une unité de traitement de données 50 reliée par un bus de données 51 à une mémoire de programme 52 et à une interface 53, elle-même reliée, par trois fils 54, 55, 56, à l'entrée de signal E, la sortie de signal S et l'entrée de sélection de mode ESM d'un émetteur/récepteur 57. Les entrées/sorties E/S1, E/S2 de celui-ci sont reliées à un enroulement 58 d'un transformateur d'isolation 59 dont l'autre enroulement 60 est relié au réseau de distribution 3. L'interface 53 est également reliée au micro-ordina­teur 9 et au terminal de télécommunications 10, déjà représentés à la Fig. 1, ainsi qu'à un dispositif de surveillance 61 d'une ligne téléphonique L. Le terminal 10 est également branché sur la ligne téléphonique L.Fig. 3 shows a block diagram of the reception device 11 of the data collection system of the invention. It essentially comprises a data processing unit 50 connected by a data bus 51 to a program memory 52 and to an interface 53, itself connected, by three wires 54, 55, 56, to the signal input E , the signal output S and the mode selection input ESM of a transmitter / receiver 57. The inputs / outputs E / S1, E / S2 thereof are connected to a winding 58 of a transformer insulation 59, the other winding 60 of which is connected to the distribution network 3. The interface 53 is also connected to the microcomputer 9 and to the telecommunications terminal 10, already shown in FIG. 1, as well as to a monitoring device 61 of a telephone line L. The terminal 10 is also connected to the telephone line L.

L'interface 53 permet à l'unité 50 d'échanger des données avec l'émetteur/récepteur 57, en particulier, avec son entrée E et sa sortie S, et de commander son mode de fonctionnement, émission ou réception, par son entrée ESM. Elle permet également d'échanger des données avec le micro-ordinateur 9 et le terminal 10. Elle permet, enfin, de lire le signal issu du dispositif de surveilance 61. Celui-ci reçoit les signaux présents sur la ligne téléphonique L et délivre sur sa sortie 62, lorsqu'au moins un signal de sonnerie apparaît sur la ligne L, un signal d'un niveau prédéterminé signifiant qu'un appel a lieu. Le terminal 9 permet, lorsque la ligne L est prise, d'échanger des données entre la ligne téléphonique L et l'unité de traitement 50.The interface 53 allows the unit 50 to exchange data with the transmitter / receiver 57, in particular, with its input E and its output S, and to control its operating mode, transmission or reception, by its input ESM. It also makes it possible to exchange data with the microcomputer 9 and the terminal 10. It finally allows the signal from the monitoring device 61 to be read. The latter receives the signals present on the telephone line L and delivers on its output 62, when at least one ringing signal appears on line L, a signal of a predetermined level signifying that a call takes place. Terminal 9 allows, when line L is socket, to exchange data between the telephone line L and the processing unit 50.

L'émetteur/récepteur 38 de chaque dispositif d'émission 15, 17, 19, 21 ainsi que celui 57 du dispositif de réception 11 est un émetteur/récepteur par courant porteur fonctionnant en modulation par saut de fréquence (FSK). Il est, par exemple, constitué d'un circuit spécialisé commercialisé par la société National Semiconductor Corporation sous la référence LM 1893. La fréquence de la porteuse est, de préférence, de 125 kHz. En mode émission, ils reçoivent sur leur entrée E un train de bits de données qu'ils transmettent, après modulation de la porteuse, à leurs entrées/sorties E/S1, E/S2. En mode réception, ils reçoivent sur leurs entrées/sorties E/S1, E/S2, un signal modulé, le démodulent et le convertissent en un train de bits qu'ils délivrent à leur sortie S. Chacun de ces deux modes de fonctionnement est sélectionné à la réception d'un signal prédéterminé sur l'entrée de sélection de mode ESM.The transmitter / receiver 38 of each transmission device 15, 17, 19, 21 as well as that 57 of the reception device 11 is a carrier current transmitter / receiver operating in frequency hopping modulation (FSK). It is, for example, made up of a specialized circuit sold by the company National Semiconductor Corporation under the reference LM 1893. The frequency of the carrier is preferably 125 kHz. In transmission mode, they receive on their input E a data bit stream which they transmit, after modulation of the carrier, to their inputs / outputs E / S1, E / S2. In reception mode, they receive on their inputs / outputs E / S1, E / S2, a modulated signal, demodulate it and convert it into a bit stream which they deliver at their output S. Each of these two operating modes is selected on receipt of a predetermined signal on the ESM mode selection input.

L'unité de traitement 30 de chaque dispositif d'émission fonctionne selon le programme enregistré dans la mémoire 32. De même, l'unité de traitement 50 du dispositif de réception 11 fonctionne selon le programme enregistré dans la mémoire 52. Ces programmes déterminent le fonctionnement du système de collecte de l'invention et, en particulier, le protocole de transfert de données entre le dispositif de réception 11 et les dispositifs d'émission 15, 17, 19, 21.The processing unit 30 of each transmitting device operates according to the program stored in the memory 32. Likewise, the processing unit 50 of the receiving device 11 operates according to the program stored in the memory 52. These programs determine the operation of the collection system of the invention and, in particular, the data transfer protocol between the reception device 11 and the transmission devices 15, 17, 19, 21.

A la mise en route d'un système de collecte sur une nouvelle installation, celui-ci fonctionne selon un mode d'initialisation dans lequel le dispositif de réception 11 affecte d'abord à chaque dispositif d'émission un code d'identification. Puis, les capteurs 14, 16, 18, 20 sont étalonnés. Le capteur de pression 14 du silo de stockage 6 est chargé successivement par plusieurs tares dont les valeurs de masse sont fournies au micro-ordinateur 9 ou au terminal 10 pour être transmises au dispositif de réception 11. Celui-ci les transmet au dispositif d'émission 15, en émettant au préalable son code d'identification. Le dispositif d'émission 15 calcule alors à partir des amplitudes prises par les signaux délivrés par le capteur 14, une table d'étalonnage qu'il stocke dans la mémoire 32. Le même processus est effectué pour le capteur de débit d'aliment liquide 16. A chaque volume de liquide distribué, on associe une valeur entrée au clavier et, une fois un certain nombre de mesures effectuées, le dispositif d'émission 17 calcule une courbe théorique d'étalonnage. On procède de même pour chaque dispositif d'émission et son capteur associé. Lorsque cette opération est terminée, le système de collecte peut fonctionner en mode courant.When a collection system is started on a new installation, it operates according to an initialization mode in which the reception device 11 first assigns each identification device an identification code. Then, the sensors 14, 16, 18, 20 are calibrated. The pressure sensor 14 of the storage silo 6 is loaded successively by several tares whose mass values are supplied to the microcomputer 9 or to the terminal 10 to be transmitted to the reception device 11. The latter transmits them to the reception device. issue 15, by first issuing its identification code. The emission device 15 then calculates from the amplitudes taken by the signals delivered by the sensor 14, a calibration table which it stores in memory 32. The same process is carried out for the liquid feed flow sensor 16. A value entered using the keyboard is associated with each volume of liquid dispensed and, once a certain number of measurements have been made, the emission device 17 calculates a theoretical calibration curve. The same is done for each transmission device and its associated sensor. When this operation is completed, the collection system can operate in current mode.

Dans le mode courant, le fonctionnement d'un dispositif d'émis­sion, par exemple 15, est le suivant. Son convertisseur 33 reçoit en permanence une tension issue du capteur associé, par exemple 14, qu'il transforme en une valeur numérique. Périodiquement, l'unité de traitement de données 30 commande le convertisseur 33 pour qu'il délivre cette valeur sur le bus de données 31. Elle lit alors cette valeur et calcule à partir de la table d'étalonnage une valeur de mesure qu'elle stocke dans la mémoire 32. Ce processus alterne avec un second processus dans lequel l'unité de traitement 30 analyse, via l'interface 34, le signal délivré par l'émetteur/récepteur 38 sur sa sortie 5 et, si celui-ci correspond à un code d'identification, l'unité de traitement 30 le compare avec son propre code. Si ces deux codes sont identiques, elle vient lire dans la mémoire 32 la valeur de mesure, constitue un message, inverse le niveau du signal sur le fil ESM et envoie ce message, via l'interface 34, sur l'entrée E de l'émetteur/récepteur 38.In the current mode, the operation of a transmission device, for example 15, is as follows. Its converter 33 permanently receives a voltage from the associated sensor, for example 14, which it transforms into a digital value. Periodically, the data processing unit 30 controls the converter 33 so that it delivers this value on the data bus 31. It then reads this value and calculates from the calibration table a measured value which it stores in memory 32. This process alternates with a second process in which the processing unit 30 analyzes, via the interface 34, the signal delivered by the transmitter / receiver 38 on its output 5 and, if this corresponds to an identification code, the processing unit 30 compares it with its own code. If these two codes are identical, it comes to read the measurement value in memory 32, constitutes a message, reverses the level of the signal on the ESM wire and sends this message, via interface 34, to input E of the transmitter / receiver 38.

Quant au dispositif de réception 11, il analyse en continu, via l'interface 53, le signal issu du terminal 10, celui issu du micro-ordinateur 9 et celui issu du dispositif de surveillance 61. Supposons qu'un appel sur la ligne L ait lieu. Après l'apparition d'au moins un signal de sonnerie, le signal de sortie du dispositif de surveillance 61 prend un niveau prédéterminé. L'unité de traitement 50 lit ce signal et envoie alors, via l'interface 53, un signal de prise de ligne au terminal 10 pour qu'il établisse sa propre connexion sur la ligne L. Celui-ci est donc prêt à recevoir des données de l'appelant et à les transmettre, via l'interface 53, à l'unité de traitement 50. De même, lorsque le dispositif de réception 11 reçoit un signal de commande directement du terminal 10 ou du micro-ordina­teur 9, ce signal est transmis, via l'interface 53, à son unité de traitement 50. Celle-ci analyse alors les données reçues et lorsqu'el­ les correspondent à un code de demande d'accès à un dispositif d'émission, par exemple 15, elle fournit à l'entrée ESM un signal de commande pour mettre l'émetteur/récepteur 57 en mode émission et émet sur son entrée E un train de bits représentatifs du numéro d'adressage du dispositif d'émission demandé. Puis, elle inverse le signal sur le fil ESM, et attend qu'un signal se présente sur la sortie 5. Ce signal correspond à la valeur de mesure issue du dispositif d'émission demandé. Il est reçu, via l'interface 53, par l'unité de traitement 50 qui la transmet alors soit au terminal 9, soit au micro-ordinateur 10, selon celui qui a effectué la demande d'accès.As for the reception device 11, it continuously analyzes, via the interface 53, the signal coming from the terminal 10, that coming from the microcomputer 9 and that coming from the monitoring device 61. Suppose that a call on the line L takes place. After the appearance of at least one ringing signal, the output signal from the monitoring device 61 assumes a predetermined level. The processing unit 50 reads this signal and then sends, via the interface 53, a line seizure signal to the terminal 10 so that it establishes its own connection on the line L. The latter is therefore ready to receive caller's data and to transmit them, via the interface 53, to the processing unit 50. Similarly, when the reception device 11 receives a control signal directly from the terminal 10 or from the microcomputer 9, this signal is transmitted, via the interface 53, to its processing unit 50. The latter then analyzes the data received and when it they correspond to a code for requesting access to a transmission device, for example 15, it supplies the ESM input with a control signal to put the transmitter / receiver 57 in transmission mode and transmits on its input E a bit stream representative of the address number of the requested sending device. Then, it reverses the signal on the ESM wire, and waits for a signal to appear on output 5. This signal corresponds to the measurement value coming from the requested transmission device. It is received, via the interface 53, by the processing unit 50 which then transmits it either to the terminal 9, or to the microcomputer 10, depending on who made the access request.

Ainsi, supposons que le fabricant appelle une installation d'élevage pour effectuer une mise à jour de ces fichiers-clients. Le fabricant effectue la numérotation de la ligne L. Après au moins un signal de sonnerie sur celle-ci, le dispositif de réception 11 établit la connexion du terminal 10 sur la ligne L. Celui-ci est donc prêt à recevoir des données du site central et à les transmettre au dispositif de réception 11. A la réception de données relatives à une demande d'accès aux dispositifs d'émission 15, 17, 19, 21, le dispositif de réception 11 récupère les valeurs de mesure stockées dans les mémoires des dispositifs d'émission et les transmet au terminal 9 où elles sont fournies, via la ligne L au site central. Elles servent alors à la remise à jour des fichiers-clients du fabricant.Thus, suppose that the manufacturer calls a breeding facility to update these client files. The manufacturer dials the line L. After at least one ring signal on the line, the receiving device 11 establishes the connection of the terminal 10 on the line L. The latter is therefore ready to receive data from the site and transmit them to the reception device 11. On reception of data relating to a request for access to the transmission devices 15, 17, 19, 21, the reception device 11 retrieves the measurement values stored in the memories transmitting devices and transmits them to terminal 9 where they are supplied, via line L to the central site. They are then used to update the manufacturer's client files.

De même, si l'éleveur veut, par exemple, connaître son stock d'aliment solide, il peut utiliser le terminal 10 ou le micro-ordina­teur 9 qui entre alors en communication avec le dispositif de réception 11. Ce dernier récupère la valeur de mesure stockée dans le dispositif d'émission 15 et la transmet alors soit au terminal 10, soit au micro-ordinateur 9. Dans ce dernier cas, elle peut être traitée informatiquement et servir, par exemple, à la mise à jour d'un fichier servant à le gestion locale de l'installation.Similarly, if the farmer wants, for example, to know his stock of solid food, he can use the terminal 10 or the microcomputer 9 which then enters into communication with the reception device 11. The latter recovers the value of measurement stored in the transmission device 15 and then transmits it either to the terminal 10 or to the microcomputer 9. In the latter case, it can be processed by computer and be used, for example, for updating a file used for local management of the installation.
